Overall Score
Based on our independent scoring across 6 dimensions, Supabase scores 89/100 overall versus PlanetScale's 87/100 — a 2-point margin. Supabase leads on Developer UX in particular. That said, PlanetScale may still be the right choice if the dimensions where it scores higher match your specific priorities — the radar chart above shows the full profile side by side.
Both Supabase and PlanetScale offer a free tier, so entry-level cost is not a differentiating factor. Compare the feature and usage limits of each free plan to see which gives you more headroom before a paid upgrade is needed.
Supabase scores higher on Price / Value — 90/100 versus 78/100 for PlanetScale. If price / value is your primary decision criterion, Supabase is the stronger choice in this head-to-head.
Switching between databases tools is generally possible but involves migration effort: exporting your data or configuration from Supabase, re-importing or reconfiguring in PlanetScale, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test PlanetScale on a non-production project first before migrating.
Supabase (89/100) is the better fit for teams who prioritise developer ux — its strongest dimension — and who want a free entry point. PlanetScale (87/100) is the better fit for teams who prioritise scalability and want a free entry point. If both dimensions matter equally, the overall score winner (Supabase) is the safer default choice.
